Vitest is a testing framework powered by Vite. Prior to 3.2.5 and 4.1.0, the Vitest UI/API server on Windows used isFileServingAllowed incorrectly for /__vitest_attachment__, allowing \\?\\..\\ path traversal to read files outside the project; exposed API write and rerun features such as saveTestFile and rerun could also allow arbitrary script execution. This issue is fixed in versions 3.2.5 and 4.1.0.
Vitest is a testing framework powered by Vite. The `__screenshot-error` handler on the browser mode HTTP server that responds any file on the file system. Especially if the server is exposed on the network by `browser.api.host: true`, an attacker can send a request to that handler from remote to get the content of arbitrary files.This `__screenshot-error` handler on the browser mode HTTP server responds any file on the file system. This code was added by commit `2d62051`. Users explicitly exposing the browser mode server to the network by `browser.api.host: true` may get any files exposed. This issue has been addressed in versions 2.1.9 and 3.0.4. Users are advised to upgrade. There are no known workarounds for this vulnerability.
